FIELD OF THE INVENTION

The present invention relates to hair cosmetics which is useful insuppressing a frictional feeling of hair during rinsing in running waterand improving the softness and smoothness of hair during rinsing.

BACKGROUND OF THE INVENTION

The required performance of hair cosmetics is varied depending on eachstage during washing, during rinsing, during wetting and after drying.There is strong demand particularly for improvement of softness andsmoothness during rinsing and suppression of friction.

Conventionally, cationic compounds such as cationic surfactants andcationic polymers, lubricants, silicones etc. have been used to improvesmoothness during rinsing, but the effect of the cationic surfactantsand cationic polymers on suppression of a feeling of friction in wateris limited, and is poor in an ability to confer softness and smoothness.The lubricants hardly suppress a feeling of friction in running water,and dimethyl polysiloxane can be said to be absent in an ability tosuppress a feeling of friction in running water and in an ability toconfer softness and smoothness. Among the silicones, apolyether-modified silicone is poor in an ability to confer a feeling ofsoftness, and the ability thereof to suppress a feeling of friction andto confer smoothness is not durable. An amino-modified silicone canconfer a lasting feeling of softness, but cancels the feeling ofselfness because of its feeling of friction similar to the feeling ofstrong rubber in running water.
